Gtr Cams Into 33gtst

[sinistaGTR]

Just wondering if its possible to put gtr cams into a S1 r33gtst, and are they any better..........

[Adriano]

cant be done without modifying the cams or going to solid lifters.

[sinistaGTR]

yeh thanks there goes that idea lol, at the moment i really dont have a spare $1k or so for cams just thought id see if there was a cheap upgrade lol

[Stronzo]

afaik with gt-r cams you`ll loose variable timing for intake camshaft.

You do lose VCT. The stock GTR cams give really doughy power delivery under 5K but over they go like a cut cat. Ivan Tighe Engineering in Brisbane can regrind the GTR cams for about $300 to give a little extra lift and profile to work with the hydraulic lifter, but you lose VCT so Poncams always seem to be the preferred choice.

No they are a larger diameter got some free with the gtr cams i bought for my rb25 Neo, i got the solid lifters so these cams can go in although the Neo cams are fairly good the gtr cam on the inlet side is slightly larger and does away with the NVCS, the exhaust has slightly larger duration on the gtr but less lift so i'm leaving that cam in just gotta get the baby going now!!!

Hope this helps!

just back on this topic...

How do you go with RB26 gear into an R32 RB25? i have just brought a 26 head with the plan to loot it & modify either an R32 or R33 rb25det head to suit.

which would be better? as i have both, and are prepared to modify anything i have to.

[R31Nismoid]

Why would you bother stripping the RB26 head?

Better off making it mate the RB25 rear end IMO

[Adriano]

Yeah, just bolt the rb26 head to the rb25 block using rb25 head bolts or arp studs
